Car body

ABSTRACT

A roof-mounted container with a base frame where electrical apparatuses can be mounted; at least one hood can be set on the base frame. Electrical apparatuses can be mounted and wired in such a roof-mounted container independently of the car body being finished.

FIELD OF THE INVENTION

The present invention relates to a car body with at least oneroof-mounted container for accommodating electrical apparatuses of thedrive and car control of rolling stock and trolley buses.

BACKGROUND INFORMATION

A roof-mounted container for a car body is described in, for example,German Patent No. 43 33 437. The roof-mounted container describedtherein accommodates electrical apparatuses and wiring, and is part ofthe car roof. Electrical apparatuses and their wiring can be mounted inthe roof container only after the car body has been finished.

Another roof-mounted container is described in German UtilityApplication 92 15 814. The housing of this roof-mounted container isformed by a rectangular bottom, two side walls, and two end walls. Thehousing can be covered by a single-piece cover, which covers the entirearea of the housing. In order to provide good accessibility to thecomponents arranged in the housing from both sides, detachablearticulations are arranged on the upper edges of both side walls. Theseallow the housing cover to be swung open from either side.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a roof-mountedcontainer that allows electrical apparatuses to be mounted and wired init in a simple manner, and independent of a car body being finished.

The roof-mounted container includes a rectangular base frame having twolongitudinal supports and two transversal supports. At least oneadditional longitudinal support and/or at least one additionaltransversal support may be arranged within the base frame. Electricalapparatuses may be mounted on the base frame. Additionally, at least onehood may be provided on the base frame The base frame is mounted on theoverhead support of the car body and is sealed against the end walls andside walls of the car body.

Through the design of the base frame, and by having the base frame andthe hood designed as separate components, electrical apparatuses, suchas traction converters and on-board electrical system converters, aswell as plates (boards) equipped with electrical apparatuses, may bemounted in the roof-mounted container. After the electrical apparatuseshave been mounted and wired, the hood may be set up. The roof-mountedcontainer can thus be pre-assembled in a simple manner. Subsequently,according to the present invention, only the roof-mounted container withits base frame is positioned on a portal support of the car body, and issealed against the end walls and side walls of the car body.

Different materials can be advantageously paired in the roof-mountedcontainer for a car body. Thus, for example, both the base frame and thehood may be made of an electrically conductive material. Theelectrically conductive materials may be different, for example, thebase frame may be made of steel, and the hood of aluminum. An improvedelectromagnetic compatibility (“EMC”) protection is thus obtained. Onthe other hand, if the base frame is made of an electrically insulatingmaterial, an intermediary potential can be advantageously built up. Thebuild-up of an intermediary potential is necessary, for example, in thecase of trolley buses (O-buses).

Improved electromagnetic compatibility is also achieved with aroof-mounted container for a car body.

In addition, in a roof-mounted container, fire-protection requirementsare met in a simple manner. At the same time, EMC protection is improvedby the use of the frame cover.

The roof-mounted container for a car body also advantageously providessuperior EMC protection through the separation of the power wiring fromthe other electric components.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1 and 2 show the base frame 1 of a roof-mounted container. In theexemplary embodiment shown, base frame 1 has a rectangular shape, andincludes two longitudinal supports 2 and 3, and two transversal supports4 and 5.

In the exemplary embodiment, two additional longitudinal supports 6 and7, and two additional transversal supports 8 and 9 are arranged in baseframe 1 These supports allow electric apparatuses and plates (componentboards) to be mounted on base frame 1 in a simple manner.

As illustrated in FIG. 2, in the exemplary embodiment of the presentinvention, base frame 1 supports an on-board electrical systemdistributor 10, a drive controller 11, an additional contact board 12and a converter board 13. Furthermore, an engine converter 14 and anon-board system converter 15 are set up on base frame 1. The centralarea of base frame 1 is kept free. A hood 16, which may be set on baseframe 1, has a channel 17 in its central area (FIG. 3), where a brakeresistor 18 is mounted.

Terminal boxes 19 and 20 are mounted at both ends of channel 17. Theterminal boxes contain the terminals for the electrical distribution,the electrical continuity, and the electrical link adapter.

The hood 16 includes hood covers 21 through 25, which can be swung openfrom the center of the car.

As shown in FIG. 4, in addition to the brake resistor 18, a battery 26,a reactor 27, and a fan unit 28 may also be arranged in the hood 16.
